The vulnerability CVE-2025-58702 in WebWizards MarketKing is a stored cross-site scripting (XSS) flaw caused by improper input neutralization during web page generation. This allows an attacker with low privileges to inject malicious scripts that may be executed in the context of other users, potentially leading to limited confidentiality, integrity, and availability impacts. The vulnerability affects MarketKing versions up to 2.0.92. The CVSS 3.1 vector indicates network attack vector, low attack complexity, requiring privileges and user interaction, with a scope change and low impact on confidentiality, integrity, and availability.

Successful exploitation could allow an attacker with low privileges to inject and store malicious scripts that execute when other users view affected pages. This can lead to limited disclosure of information, modification of data, and disruption of availability within the affected application context. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
